MobileIron Core

MobileIron Core

Netskope supports using MobileIron Core for mobile device management (MDM) to allow iOS devices access to the Netskope cloud using the on-demand VPN mode. This document explains how to deploy Netskope for iOS devices using the on-demand and per-app VPN mode, and how to deploy Android Managed Configurations.

Note

Refer to your MobileIron Administration guide for additional help.

Prerequisites

To deploy MobileIron for iOS VPN, you can get the Netskope Root and Intermediate CA certificates from Netskope, or use your own Root and Intermediate certificates.

In the Netskope tenant UI, go to Settings > Security Cloud Platform > Netskope Client > MDM Distribution. In the Certificate Setup section of this page, download the Netskope Root and Intermediate certificates. If using your own certificates, downloading these certificates are not necessary. In either case, copy the tenant OU and Organization Name here. These are needed when enrolling the local certificate.

In the Create VPN Configuration section, copy the VPN Server Name, Organization ID, and PAC URL. These are needed for configuring the VPN profile. This page also shows the current VPN mode configured. Optionally, your administrator can have the on-demand VPN function set to always on therefore not requiring the connection to be triggered each time.

In the Upload Certificate section, upload new certificates to Netskope, or view and replace an existing certificate using the icons to the right of the registered certificate.

Configure MobileIron Core for iOS VPN

The following sections explain how to upload and enroll certificates and how to configure an iOS profile for MobileIron Core for on-demand or per-app VPN. For information about iOS VPN fail-open, refer to iOS VPN Fail Open.

Upload and Enroll Certificates

To upload and enroll certificates for MobileIron on-demand and per-app VPN:

  1. To upload the Local CA certificate, open the MobileIron Core UI and go to Services > Local CA > Add > Intermediate Enterprise CA.
  2. Upload the CA certificate with the key in PFX format. Use either your own CA cert with key, or create a self-signed certificate in MobileIron (Services > Local CA > Add > Generate Self-Signed Certificate). Browse to and select the certificate file, enter a Local CA Name, and then click Upload Certificate.

    Note

    This Certificate has Root CA and Intermediate certificate in PFX format, and it is used by SCEP to issue end-user certificates at VPN Configuration setup while installing the profile on to the user’s device. A Certificate Authority (CA) issues the end-user certificates.

  3. To upload the Root certificate, go to Policies & Configs > Add New > Certificates. In the New Certificate Setting window, enter the certificate name and description, browse to and select the certificate file.

    Note

    While uploading a certificate, leave the Password and Confirm Password options empty. And if using the Netskope provided Root certificate, the file name is rootcaCert.pem.

    When finished, click Save.

  4. To upload the Intermediate CA certificate, repeat step 3. If using the Netskope provided Intermediate certificate, the file name is caCert.pem.
  5. To configure the local certificate enrollment, go to Policies & Configs > Add New > Certificate Enrollment > Local.
  6. Enter these parameters:
    • Name: Enter your Local Certificate Enrollment profile name. This is the VPN MobileIron configuration name.
    • Certificate Type: Select User Certificate.
    • Local CAs: Select the certificate that you uploaded in step 1 above.
    • Subject: Enter the following code string in this format:
      emailAddress=$EMAIL$,CN=$EMAIL$,OU=<Tenant OU>,O=<Organization Name>,L=<Location>,ST=<State>,C=<Country>

      Use the OU and O values from the Certificate Setup dialog box in the Netskope UI (Settings > Security Cloud Platform > Netskope Client > MDM Distribution).

      Important

      Location (L), State (ST), and country (C) must be unique for your CA.

    • Subject Common Name: Optional. To use, select from the dropdown list.
    • Key Usage: Optional. Choose to enable or disable.
    • Key Size: 2048
    • CSR Signing Algorithm: SHA1

      Note

iOS VPN Fail-Open

Fail open function allows traffic from a device using iOS VPN to bypass Netskope and directly go to an app or service. When fail open is enabled, all iOS devices will no longer steer traffic to Netskope. Fail open occurs when Netskope initiates it due to a service interruption and when an admin enables it in the Netskope UI.

To enable fail open for iOS VPN:

  1. In the Netskope UI, go to Settings > Security Cloud Platform > MDM Distribution.
  2. In the Create VPN Configuration section, confirm that your iOS VPN is operational. If so, click the ToolIcon.png icon to open the Advanced Configuration dialog box.
